Derek Kyostia, an interpretative guide with Tide Rip Grizzly Tours. Tide Rip Grizzly Bear tours offer wildlife tours in Knight Inlet to find bears in the spring. As the snows melt, both black and grizzly bears emerge from their hibernation dens on the mountain slopes. Hungry bears make their way down to feed on the spring sedge grasses in the river lowlands. Sedges have 20% vegetable protein value, enough to sustain the bears. The flat bottom viewing boats allow the tour operators to bring guests into very shallow areas and hopefully closer to the wildlife for safe viewing. Tours depart daily from Telegraph Cove on Vancouver Island.
